The prevailing study aimed to assess the brassinolide, and moringa leaf extracts’ foliar application influence on the growth and mineral content of local lemon transplants, commencing in 2022 in a wooden lath house affiliated with the Department of Horticulture and Landscape Gardening, College of Agriculture, University of Anbar, Ramadi, Iraq. The experiment’s study factors comprised foliar application of growth regulator brassinolide (B0, B1.0, B1.5, and B2.0 mg L^-1) and moringa leaf extracts (M0%, M2%, and M4%) on local lemon. Study elements influenced all characteristics, especially foliar spraying of brassinolide (B1.5 mg L^-1), significantly enhancing the number of secondary shoots increment and leaves, leaf area, and leaves’ nitrogen, phosphorus, potassium, and total chlorophyll content. The growth regulator brassinolide (B1.0 mg L^-1) revealed considerable secondary shoot length increment superiority. On spraying of moringa leaf extracts, moringa extract (M4%) achieved a substantial superiority in all the studied traits.
